CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. patent application Ser. No. 13/053,800, filed Mar. 22, 2011 (pending), which is incorporated herein in its entirety.

BACKGROUND

The disclosure relates to computer network-based communications in general, and in particular to real-time collaboration systems.

Real-time collaboration systems, such as instant messaging systems, are increasingly used within and between businesses and other organizations to enhance communications and cooperation between parties. Typically, before two parties can communicate with each other, each party must provide his or her collaboration system with an identifier that the collaboration system uses to identify the other party. Common examples of such identifiers include email addresses and collaboration system-specific user IDs, which are typically maintained in contact lists. Collaboration systems typically provide their users with “presence” notifications regarding the current status of the contacts in their contact lists, such as whether or not a contact is currently logged-in to his/her collaboration system and available to receive communications.

BRIEF SUMMARY

In one aspect of the disclosure, an addition of an identifier to a contact list can be detected. The identifier can identify an entity in a first collaboration system. Data can be searched to find a different identifier that identifies the entity in at least a second collaboration system. The different identifier can be added to the contact list.

In one aspect of the disclosure, a contact list can be established in a first collaboration system. The contact list can include at least one record for an entity. A second collaboration system remotely located from the first collaboration system can be searched for one or more identifiers of the entity. One or more identifiers can be presented via a user interface resulting from the searching. The presenting can occur automatically without a user of the user interface manually inputting the one or more identifiers of the entity. A user selectable option can be provided to add the one or more identifiers to the contact list. Responsive to a user selection of the user selectable option, at least one of the one or more identifiers can be added to the contact list. In absence of the user selection of the user selectable option, the one or more identifiers are not added to the contact list.

Systems and computer program products embodying the above aspects are also provided in the disclosure.

DETAILED DESCRIPTION

It is increasingly common for an individual collaboration system user to have multiple identities, each of which is specific to a different collaboration system, where the user may be logged-in to different collaboration systems at different times. Thus, a collaboration system user who wishes to receive presence notifications regarding a contact who has multiple identities must add each of the contact's multiple identities to his/her contact list. Unfortunately, the user might not be aware that the contact has multiple identities or what these multiple identities are. This problem with conventional approaches was discovered by the inventors of the disclosure in the course of developing the invention.

One embodiment of the disclosure is for managing a contact list in a collaboration system, by detecting the addition of an identifier to a contact list. The identifier can identify an entity in a first collaboration system. Data can be searched to find an identifier that identifies the entity in at least a second collaboration system. The identifier that identifies the entity in the second collaboration system can be added to the contact list.

Reference is now made to FIG. 1 which is an illustration of a system for managing a contact list in a collaboration system, constructed and operative in accordance with an embodiment of the invention. In the system of FIG. 1, an addition detector 100 is configured to detect the addition of an identifier to a contact list 102, such as a contact list of a collaboration system (hereinafter “collaboration system A”) like IBM Lotus Sametime™, commercially-available from International Business Machines Corporation, Armonk, N.Y. The identifier (hereinafter “the identifier being added”) may, for example, be added to contact list 102 by a user 104 of collaboration system A using a contact list manager 106, where the identifier being added identifies an entity, such as a user 108, belonging to collaboration system A, or belonging to a different collaboration system, such as Yahoo Messenger™, commercially-available from Yahoo! Inc., Sunnyvale, Calif. As used herein, detecting the addition of an identifier to a contact list can mean either detecting the presence of the identifier within the contact list after it has been added to the contact list, and/or detecting any action related to adding the identifier to the contact list even before the identifier is actually inserted into the contact list.

An alias searcher 110 is configured to search data to find one or more identifiers, other than the identifier being added, that identify user 108 in one or more collaboration systems that are external collaboration system A with which collaboration system A communicates, such as via a gateway 112. Alias searcher 110 preferably conducts its search responsive to addition detector 100 detecting the addition to contact list 102 of the identifier being added identifying user 108. Alias searcher 110 preferably searches an index 114 of user identifiers that includes one or more groups of user identifiers, where a group of identifiers includes one or more identifiers identifying the same user. Index 114 may be populated by a user identifier retrieval agent 116 that is configured in accordance with conventional techniques to search computer-based documents in which the identifier being added of user 108 appears, such as email messages and chat histories, to find other identifiers that identify user 108, such as in signature portions of such documents. Additionally or alternatively, alias searcher 110 may itself search such computer-based documents to find other identifiers that identify user 108. Alias searcher 110 preferably presents any identifiers it finds for selection, such as via a computer display for selection by user 104, whereupon contact list manager 106 adds the selected identities of user 108 to contact list 102.

A subscriptions manager 118 is preferably configured to request or otherwise create subscriptions for information regarding user 108, such as for presence notifications regarding the current status user 108, where each of the subscriptions is associated with a different identifier that identifies user 108. Thus, for example, one subscription may be associated with the identifier being added to contact list 102 that was detected by addition detector 100, whereas one or more other subscriptions may be associated with one or more of the other identities of user 108 that were found by alias searcher 110 and selected for addition to contact list 102. Subscriptions that are associated with identifiers that identify user 108 in one or more external collaboration systems with which collaboration system A communicates via a gateway 112 are preferably managed through gateway 112 in accordance with conventional techniques.

Any of the elements shown in FIG. 1 are preferably implemented by one or more computers, such as a computer 118, by implementing any of the elements shown in FIG. 1 in computer hardware and/or in computer software embodied in a non-transient, computer-readable medium in accordance with conventional techniques.

Reference is now made to FIG. 2 which is a flowchart of a method of operation of the system of FIG. 1, operative in accordance with an embodiment of the invention. In the method of FIG. 2, the addition of an identifier (hereinafter “the identifier being added”) to a contact list is detected, such as of an identifier that identifies a user of a collaboration system A (step 200). A search is conducted to find one or more identifiers that identify the same user, such as in other collaboration systems that are external to collaboration system A (step 202). Identifiers found during the search are preferably presented for selection, such as by the user to whom the contact list belongs (step 204). Selected identifiers are added to the contact list (step 206). One or more subscriptions are requested or otherwise created for one or more of the identifiers (step 208). Subscriptions that are associated with identifiers that are associated with one or more collaboration systems that are external to collaboration system A are managed through a gateway of collaboration system A (step 210).

Reference is now made to FIGS. 3A and 3B, which are illustrations of interfaces for use in an operational scenario of the system of FIG. 1 and the method of FIG. 2 in accordance with an embodiment of the invention. In FIG. 3A a window 300 is used by a contact list owner to add the email address of a contact to the contact list. In FIG. 3B a window 302 is presented indicating that one or more additional email addresses were found for the contact being added that identify the contact in collaboration systems belonging to other user communities. The contact list owner is invited to select one or more of the email addresses to be added to the contact list in association with the contact.

Referring now to FIG. 4, block diagram 400 illustrates a hardware implementation of a computing system in accordance with which one or more components/methodologies of the invention (e.g., components/methodologies described in the context of FIGS. 1-2) may be implemented, according to an embodiment of the invention.

As shown, the techniques for controlling access to at least one resource may be implemented in accordance with a processor 410, a memory 412, I/O devices 414, and a network interface 416, coupled via a computer bus 418 or alternate connection arrangement.
